I did this and I did not get any error. BUT, dmesg shows errors with the
loading of modules (INITIAL proSLIC failed or something like that). I
switch the modules around, and the error followed the module (pointing me
to a module problem, not a TDM400 probem).
Turns out I have an RMA now with Digium, so it`s defective hardware (at leas
in their opinion, which is good enough for me). Thank you for your reply, I
really appreciate the level of support I am getting from volunteers like
you.
